CAP1293

3-Channel Capacitive Touch Sensor with Proximity

Detection & Signal Guard

General Description

Applications

The CAP1293 is a multiple channel capacitive touch

sensor controller. It contains three (3) individual capac-

itive touch sensor inputs with programmable sensitivity

for use in touch sensor applications. Each sensor input

is calibrated to compensate for system parasitic capac-

itance and automatically recalibrated to compensate

for gradual environmental changes.

• Desktop and Notebook PCs

• LCD Monitors

• Consumer Electronics

• Appliances

Features

In addition, the CAP1293 can be configured to detect

proximity on one or more channels with an optional sig-

nal guard to reduce noise sensitivity and to isolate the

proximity antenna from nearby conductive surfaces

that would otherwise attenuate the e-field.

• Three (3) Capacitive Touch Sensor Inputs

- Programmable sensitivity

- Automatic recalibration

- Calibrates for parasitic capacitance

- Individual thresholds for each button

• Proximity Detection

The CAP1293 includes Multiple Pattern Touch recogni-

tion that allows the user to select a specific set of but-

tons to be touched simultaneously. If this pattern is

detected, a status bit is set and an interrupt is gener-

ated.

• Signal Guard

- Isolates the proximity antenna from attenua-

tion

- Reduces system noise sensitivity effects on

inputs

The CAP1293 has Active and Standby states, each

with its own sensor input configuration controls. The

Combo state allows a combination of sensor input con-

trols to be used which enables one or more sensor

inputs to operate as buttons while another sensor input

is operating as a proximity detector. Power consump-

tion in the Standby and Combo states is dependent on

the number of sensor inputs enabled as well as averag-

ing, sampling time, and cycle time. Deep Sleep is the

lowest power state available, drawing 5µA (typical) of

current. In this state, no sensor inputs are active, and

communications will wake the device.

• Multiple Button Pattern Detection

• Power Button Support

• Press and Hold Feature for Volume-like Applica-

tions

• 3.3V or 5V Supply

• Analog Filtering for System Noise Sources

• RF Detection and Avoidance Filters

• Digital EMI Blocker

• 8kV ESD Rating on All Pins (HBM)

• Low Power Operation

- 5µA quiescent current in Deep Sleep

- 50µA quiescent current in Standby (1 sensor

input monitored)

- Samples one or more channels in Standby

• SMBus / I²C Compliant Communication Interface

• Available in an 8-pin 2mm x 3mm TDFN RoHS

compliant package

• Available in an 8-pin SOIC RoHS compliant pack-
